TM520 Timer Module

The TM520 provides an output that can be activated based on a delay time. If either the keyswitch on the module is activated, or a predefined event within the control panel occurs then a timed delay (set between 10 minutes and 2 hours 10 minutes) is started.

When the delay reaches zero the TM520 output is activated. The unit sounds an internal buzzer and shows a red LED when the output is active, and shows a yellow LED when the timer is counting down. To provide a warning that the delay is nearly over, the red LED and the buzzer will pulse 5 minutes before the end of the delay.

The TM520 requires a separate 24V DC supply to operate. The module is not addressable and will therefore not take an address on the loop.
